摘要
Abstract
Study of metallogenic epoch , temperature and composition of the fluid inclusions in different deposits in Xiazhuang ore field indicated that the uranium deposits were with the same ore‐forming flu‐id.Mineralization in Xiazhuang ore field can be divided into three stages.The first metallogenic stage was happened at 138Ma by alkaline fluid with high temperature , and the ore body was controlled by EW‐trending structure. The second metallogenic stage was happened at 96.4 ~ 81 Ma by acidic fluid with moderate‐to‐low temperature ,and the ore body was controlled by NE‐trending structure.The third met‐allogenic stage was happened at 61 Ma and the ore body was reformed from old ore body.Based on the structure and magma evolution , A 3D structure controlling metallogenic model was established for Xi‐azhuang uranium ore field. The deposit was believed to be formed by supposition of several stage mineral‐ization and the favorable exploration place is the tensional part of the later derived fracture of the early main structure. There were EW strike basement structure filled with basic rock veins in Xiwang deposit , therefore there are potential to find orebody in the deep of the deposit.关键词
